Question

compute.
-3.53 + 46.78 =
-52.6 + (-84.7) =

Explanation:

Step1: Calculate \(-3.53 + 46.78\)

To add a negative number and a positive number, we subtract the absolute value of the negative number from the positive number (since \(46.78\) has a larger absolute value than \(3.53\)). So, \(46.78 - 3.53 = 43.25\).

Step2: Calculate \(-52.6 + (-84.7)\)

When adding two negative numbers, we add their absolute values and keep the negative sign. So, \(52.6 + 84.7 = 137.3\), and then we add the negative sign, giving \(-137.3\).

Answer:

For \(-3.53 + 46.78\), the answer is \(43.25\).
For \(-52.6 + (-84.7)\), the answer is \(-137.3\).
